At the end of a month or the beginning of a new month, I'm always busy supporting my colleagues in the finance and HR departments who are trying to calculate data and salaries as quickly as possible before payday. Like today, I had to make sure there were no problems while they were using the OA system.
Last month, a colleague in the finance department found an error in the OA system after she finished her work. She had manually fixed the her problem in her Excel file. The error was in the SQL script of a report that was missing a filter condition to pass the unwanted data. I had fixed it last month, but had not tested it.
The colleague asked me to test it before she use the report today. I spent the whole morning testing the report. It seems to work.
